, obama, romney, who's the better debater both have clear debate skills and shown those in their debates over the time. governor romney had very good debates in the republican primaries against his opponents and was very effective in those. president obama had some pretty good debates particularly the general election debates against senator mccain. the new format they're using i'm not sure it favors either candidate. it gives president obama a little bit more opportunity to talk at length which he wants to do about his record and about the things he's going to do going forward and also to draw some contrast with governor romney. for governor romney it may give him an opportunity rather than looking like he has canned answers to show people he's more thoughtful and warmer and more likable. >> dan balz, both warm and likable. thank you very much. thanks for being with us. >> thanks. >> up next, new questions about security and intelligence behind the benghazi terror attack. former ambassador to iraq chris hill joining us live here in denver. you're watching "andrea mitchell reports" only
